Title: Pretreating sintered metal parts before electroplating - using reagents to obtain ppt of colloidal silica which seals the pores
IPC: C25D5/34
Filed: 1974-09-27
Abstract: Process for the treatment of sintered metal parts intended for electroplating with metals, the process consisting essentially of impregnating the parts with a first chemical cpd., and then using a second cpd. to form an inert, insol. ppte with the first cpd., the ppte. sealing the inlets of the pores in the sintered metal. The first cpd. is pref. a soln of sodium silicate, whereas the second cpd. is pref. a weak acid, esp. acetic acid. The sintered parts are pref. carefully washed after impregnation with the first cpd., and, after using the second cpd., washed and dried. Pretreatment of sintered parts having a porosity of e.g. 20-25% prior to electroplating e.g. with Zn or Cd. the treatment prevents to electroplating e.g. with Zn or Cd. The treatment seeping out at some later date; this method is an improvement on paraffin wax and it is very difficult to remove the latter prior to electroplating.

Title: Improved selective calling system for radio communications - uses different pulse recurrence frequencies for each receiver
Inventor: SEVERI DIDIER
IPC: H04W88/02
Filed: 1974-11-21
Abstract: The system comprises a high frequency transmitter with a radiating loop, and a number of receivers. The transmitter is modulated at a low frequency with pulses of equal length, but with a different recurrence frequency for each receiver. The receiver detector (10) is followed by a monostable circuit (12) with a different rundown time for each receiver, so that it can only receive a second pulse at an interval corresponding to its assigned pulse recurrence frequency. When this happens the gate circuit (16) opens and the transistor (18) feeds power to an oscillator which produces an audible signal.

Title: Recirculating ball screw drive - with staggered return paths cut in nut wall to improve load distribution
IPC: F16H25/22
Filed: 1975-10-14
Abstract: The channels for the balls (31) in the nut (15) are semicircular in cross section as they are in the shaft matching the diameter of the balls. The ends of the channel in any set are connected together by recessing the groove further into the nut, so that the balls can recirculate over the lands between the shaft grooves. This portion of the channel is angled in the opposite direction to that of the normal part of the thread, relative to the shaft axis. The recirculating channels of each set are staggered in angular position around the shaft, this improving bad distribution.

IPC: F16H15/04
Filed: 1976-02-18
Abstract: The speed reduction gear has an input shaft with a pinion meshing with the pinion (4) of the layshaft (5). The layshaft carries a rotor composed of a number of discs (30, 30a) with balls (9) retained in slots formed in the discs.

Title: Valve for fuel injector of IC engine - has sealing zone restricted by two parallel edges
IPC: F02M61/18
Filed: 1976-10-20
Abstract: The valve of a fuel injector for an internal combustion engine consists of a valve head (12) sliding in a cylindrical body (10). A spring presses the valve head (12) onto the seat (13) to seal off the orifices (15). The valve is opened by the pressure of the fuel supplied through the passage-way (16) acting on the underside of the valve head. A shallow groove (14) is formed in the conical surface of the valve head so that so parallel sharp edges are formed. When the valve is closed these edges form a seal on each side of the orifices (15). The edges can deform under the sealing pressure to accommodate dimensional inaccuracies.

Title: Gas pipe leak checking system - generates vacuum after isolation from mains and monitors pressure rise
IPC: G01M3/28
Filed: 1976-10-21
Abstract: The system is used to check gas pipes inside dwelling houses for leaks. The distribution pipes are first isolated from the mains, and a vacuum is then generated inside them, after which the rate of pressure rise is monitored. After generation of the vacuum a tracer gas can be introduced into the piping and leaks found by using a detector sensitive to this tracer gas. The pipes can also be connected to a reference leak, whose rate of leakage is equal to the minimum threshold value of the leaks to be detected. This leak unit can be mounted at the highest point, and can be detachable, so that the gas fitter can take it with him.
